openssl - security update

Multiple vulnerabilities have been discovered in OpenSSL, a Secure
Sockets Layer toolkit. The Common Vulnerabilities and Exposures project
identifies the following issues:

• CVE-2014-3569
  Frank Schmirler reported that the ssl23_get_client_hello function in
  OpenSSL does not properly handle attempts to use unsupported
  protocols. When OpenSSL is built with the no-ssl3 option and a SSL
  v3 ClientHello is received, the ssl method would be set to NULL which
  could later result in a NULL pointer dereference and daemon crash.
• CVE-2014-3570
  Pieter Wuille of Blockstream reported that the bignum squaring
  (BN_sqr) may produce incorrect results on some platforms, which
  might make it easier for remote attackers to defeat cryptographic
  protection mechanisms.
• CVE-2014-3571
  Markus Stenberg of Cisco Systems, Inc. reported that a carefully
  crafted DTLS message can cause a segmentation fault in OpenSSL due
  to a NULL pointer dereference. A remote attacker could use this flaw
  to mount a denial of service attack.
• CVE-2014-3572
  Karthikeyan Bhargavan of the PROSECCO team at INRIA reported that an
  OpenSSL client would accept a handshake using an ephemeral ECDH
  ciphersuite if the server key exchange message is omitted. This
  allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks
  and trigger a loss of forward secrecy.
• CVE-2014-8275
  Antti Karjalainen and Tuomo Untinen of the Codenomicon CROSS project
  and Konrad Kraszewski of Google reported various certificate
  fingerprint issues, which allow remote attackers to defeat a
  fingerprint-based certificate-blacklist protection mechanism.
• CVE-2015-0204
  Karthikeyan Bhargavan of the PROSECCO team at INRIA reported that
  an OpenSSL client will accept the use of an ephemeral RSA key in a
  non-export RSA key exchange ciphersuite, violating the TLS
  standard. This allows remote SSL servers to downgrade the security
  of the session.
• CVE-2015-0205
  Karthikeyan Bhargavan of the PROSECCO team at INRIA reported that an
  OpenSSL server will accept a DH certificate for client
  authentication without the certificate verify message. This flaw
  effectively allows a client to authenticate without the use of a
  private key via crafted TLS handshake protocol traffic to a server
  that recognizes a certification authority with DH support.
• CVE-2015-0206
  Chris Mueller discovered a memory leak in the dtls1_buffer_record
  function. A remote attacker could exploit this flaw to mount a
  denial of service through memory exhaustion by repeatedly sending
  specially crafted DTLS records.

For the stable distribution (wheezy), these problems have been fixed in
version 1.0.1e-2+deb7u14.

For the upcoming stable distribution (jessie), these problems will be
fixed soon.

For the unstable distribution (sid), these problems have been fixed in
version 1.0.1k-1.

We recommend that you upgrade your openssl packages.
